Week 1/2
Don't be cynical or naive when judging claims and statistics
What is Critical
This central tendency avoids the bias of a genius
What is the Median
A good measure has both
What is reliability and validity
That's inconceivable! to capture
What is the Population of Interest
Based on our sample, we can estimate the population's characteristics falls between
What is a confidence interval
Used to make inferences based on a smaller group of data...about a possibly larger one
What is Inferential Statistics
Near, far, wherever you are, this measure of variability measures the distance
What is the Range
Time after time, this measure of reliability examines it
What is test-retest reliability
Every 100th caller
What is systematic sampling
A theoretical distribution built on infinity and beyond
What is a sampling distribution
This level of measurement judges the best, the worst, and everyone in between
What is Ordinal level of measurement
No skew left or right
What is normal (shape of your data/distribution)
This measure of validity looks across the universe of items
What is content validity
Keep calm and infer onward
What is probability sampling
Normally, the area under this curve
What is 1
Being the least judgmental, this level of measure simply groups characteristics
What is Nominal level of measurement
Your data's shape is tall and thin
What is Leptokurtic
If one of these things is not like the other, this measure of reliability might be low
What is internal consistency reliability
Bob Ross tells us there is only happiness in this type of sampling
What is Accidental sampling
Even though it doesn't look normal, this theorem lets us use the normal distribution to estimate the population's characteristics
What is Central Limit Theorem
You might want to use an Uber to get to the distances between these charted bars
What is a bar chart
This standard measure of variability is influenced by outliers
Drop the mic and enter a quiet room, why?
What is, if you cannot establish reliability
Substitute teachers may like this type of sampling
What is sampling with replacement
This type of error is super rare at +/-3
What is standard error
